ATTACHMENT TOR :ROTARY CLIrPER MACHINEs.

Application iefi'Aprii 2,

T o all whom t may concern.' v

Be it known that I, FREDRICK GORDON STUART,y a citizen of the United States, and residing at Washington, District oi'Columbia, have invented a nevv and useful Attach-KV ment -for a Rotary Clipping Machine, 4of which the following is a specilication.

Theobject of my invention ,isl tO provide an attachment which Will be readily applied tov any of the rotary clipper machines noW on the market, Which Will make it possibleto use such machines for the purposefof Operating a bufhng or grinding Wheel, Whereby to double the usefulness of such machines.

c It isfurther an Object of my invention to 1 provide a device of this characterL of relatively simple construction,

`The accompanying drawingA is a vertical.

section through the device, 'with a b'uii'ng Wheel which is designed to be attached to it,

Lshown in vdotted lines.

Referring to the drawing, l designates the usual flexible chain of the rotary clipperk machine; having the usual flexible tube or cover 2 and chain l having a hook attached to the revolvable head 5 which I have provided and which is mounted in a suitable `casing 6 having a tapered shank which is releasably secured in the' conventional steel collar or holder 3 of the rotary clipper machine. I provide suitable ball bearings 9 Lil) ' ing- 11 extending longitudinallyA inward" for the revolvable head lI yfurther provide a suitable voil channel lO'in head 6. I

may also provide an'oilchannel 10a' in member 6,]but this oil Vchannelis optional and preferably may be omitted. I'provide a suitable collar 7 secured to the threaded poition 8 of the bearing 6, and including a chambered inner portion for the reception of the lower set of ball bearings 9 as illus-v trated. Ivfurther provide a threaded' openconventional steel collar of the lrotary clipprojects beyond' the end of the nut or collar In operating the device members 7, 6 and 5,- attached to eachother, are inserted in the 1921. serial No. 458,154.

per machine, andthe hook'llfof. the flexible l chain of the rotary`clippery is attac-hed to the end of the revolvable head 5. '-Ihebuf-y ing'wheel 14C is thus secured to the outer 'end 15 of the revolvable head by the. screw 122" Whichv engages in "the or buliing Wheel can thus be readily applied to standard rotary clipperfmachinesv so that they owner of one oftthese machines may have the advantage of a buiiing device as Well as a clipping device The revolvable head 5 is suited .for attachmentofany v,desiredemery correspondingly i l threaded channel-l1 in head 5. An emery i wheel or buiiing Wheel, permitting utilization of the device for sharpening such de?,

vices as mowing' machine knives Without the i inconvenience of removing them from their mounting; and for other purposes for Which this attachment is applicable.

What I claim is'- l. An attachment for a rotary clipper machine, comprising a revolvable head engage-v able to the end of the iieXible rotating chain of theclipper machine, a casing member and j bearing for therevolvable head,said casing y member being ofk frusto-conical shape and slidlably detachable `lrom'ank'dfrictionallypngageable on the collar of therotary' clipper machine, a collar Securedl tothe end'of the casing, the revolvablel head.y projecting slightly beyond said cap, and means for attaching a suitable operating member such'as a bufing Wheel to the end lofthe revolvable head! 2. In an. attachmeritrtor a rotary clipper 4 machine, the combination of a revolvable head releasably attachable to the flexible rotating chainof a rotary clippermachine, a casing member forsaidrevolvable head, said casing member having a tapered shank frictionably' engageable; on .and releasably attachable to the collar ofthe rotary clipper machine',y the -revolvable head beingprovided with kanl enlarged sectionand the casing with a recessed' section to provide bearing portions, ball :bearings interposed therebetween, lan end collar releasably attached' to j 100 Within the casing, and means for securing a buiiing Wheel or similar device to the Outer f the casing and securing the revolvable ,head

end of the'revolvable head.y FREDRICK GORDONSTUART.
